Attention: Contamination!

3

Particulate

Particle contamination in a compressed air system comprises Atmospheric dirt, micro-organisms, rust and condensate depositsMuch of the contamination is less than 40 millionth of a meter in size(40 micron) and thus remains hidden from the human eye.

Parker Zander “GL-Filter series Improvement in flow characteristics – Air Flow Management

23

Improving the air inlet to the filter element

• Where air flows across a sharp edge, turbulence can occur.

This leads to increased resistance to flow and an insufficient distribution of the air flow.

• The current filter element design, also true of Zander

The air entering the element is directed through a sharp 90° angle. Turbulence, pressure drop, insufficient distribution of the air throughout the filter media is the result.

Such rapid changes in direction lead to turbulent flow, system pressure drop and increased running costs.

24

• Improvement – rounded corners reduce turbulence. The air flow however still doesn`t flow into the element in an even manner.

Improving the air inlet to the filter element

25

Improving the air inlet to the filter element – Aerospace Technology!• Optimum solution – The addition of

deflector-vanes in the air-inlet and a conical air dispenser at the base of the element prevent turbulence by maintaining an even flow distribution at a minimum pressure drop.

• Hard to believe, but its true!

Compare a conventional 90° angle and the savings of up to 75% to be gained from turbulence-free flow

26

The optimum combination

• Deflector-vanes direct the air flow in an unrestricted even-manner into the filter element.

April 22, 2023

Parker Zander “GL-Filter series” Filter element construction - Inlet-/Outlet

28

• Free-flow, turbulence-free transition of the air entering the filter element. No knife-edges.

• The inlet channel to the filter element (top end-cap) matches the inlet diameter of the filter housing.

• The top end-cap seals with the aid of two o-rings, above and below the opening.

Air inlet – Do away with energy-killers: Conical “full-flow” filter housing inlet

29

• “its plain sailing”: Airospace deflector-vanes enable the air to flow evenly into the filter element.

• “Go with the flow” - Optimum air distribution throughout the entire filter element with the aid of a flow distributor protruding into the heart of the element. This unique construction ensures full utilisation of the entire surface area.

Air inlet – “Its plain sailing”: Flow disribution

30

• A conical soft-air disperser at the base of the filter element prevents turbulence and directs the flow out through the filter media in an even manner.

No impact on the base of the element!

31

• External air stabilisers, located on the filter element top end-cap ensure the even flow of compressed air exiting the filter housing.

A “successful escape!”

April 22, 2023

Parker Zander “GL-Filter series” Filter Media

33

• High-efficiency filter media manufactured from borosilicate nano-fibres with a voids volume of 96%.

• A special “oleophobe” coating is applied to the filter media to actively repel oil and water.

• What is nano-technology? Nano comes from the Greek word “nanos”, meaning dwarf. 1 Nano = 1m/1.000.000.000. Nano technology is a particular desigb in atomic and molecular dimensions. Nano technology is not a new product, but a manufacturing technology!

The Filter Media – Nano-Technology!

Parker Zander incorporates borosilicate nano-fibre technology into it´s current range of filters and into the new GL-filter generation. We termed this material „borosilicate microfibre“ in the past. The change in name is indicative for the development in analytical methods which make it possible to establish the presence of nano-fibres in the material previously refered to as micro-fibre. As the technology exists to proove the presence of such fibres, we now term this filter media „Nano-fibre.“

34

• Deep-bed pleating techniques result in 4,5 times more effective filtration area than conventional filter elements – resulting in increased particulate retention, reduced space and lower operating costs

Large area – greater outcome!

36

• The surface area of the filter media has been optimised using deep-pleat technology. A pioneering manufacturing process representing considerable technological advancement.

• No “glued seam” – now replaced by ultra-sound welding.

Parker Zander “GL-Filter series” Why change a winning concept?

38

Compressed air must not only be clean, but also efficient!

As well as the removal of contamination, the economicsof using compressed air filters plays an important role.Here the requirement is one of minimising costs andachieving a balance between the compressed air quality being sought and the amount of energy necessary to achieve it.

The international standard for compressedair quality provides a simple, clear system for the classification of the three main sourcesof contamination, namely, water, oil and particulate.

39

Quality requirements - ISO 8573.1

Previous specification

QUALITY CLASS DIRT CONCENTRATIONParticle size in micron mg/m³

1 0,1 0,12 1 13 5 54 15 NOT DEFINED

IS0 8573 : 1991, Part 1 for particle contamination

In the 1991 edition, the specification states a maximum particle size and a concentration. The 2001 edition however states a maximum quantity of particles per cubic-meter. In order to appreciate the increase in the demand made on air quality between these dates, the 1991 particle concentration csn be converted into the particle quantity.

40

QUALITY CLASS EDITION 2001, "X-TIMES" CLEANER THAN IN EDITION 19910,1 - 0,5 Micron

1 1,9 Billion times cleaner than class 1 in 19912 19.000 times cleaner than class 2 in 19913 7.000 times cleaner than class 3 in 19914

This technique shows how much cleaner the 2001 classification is, compared with 1991.

In accordance with this statement, class 1 in the 1991 edition became class 2. In accordance with the 2001 edition it was only possible to achieve class 1 with a sterile air filter!

Quality requirements - ISO 8573.1

41

The new edition of ISO 8573.1 establishes considerable higher limits for particulate contamination. At first glance, this looks like a worstening of the recommended purity classes!

Industrial end-users will profit from the new edition of ISO 8573.1. It establishes more realistically achievable values. It is however advisable to agree which edition of ISO 8573.1 is being referred to when agreements are being made!

Quality Requirements - ISO 8573.1:2010

Compressed air quality in accordance with class 1 for particulate means: Per m³ of compressed air, the particle quantity should not exceed 20.000 particle in the size range 0,1 to 0,5. (400 particles in the size range 0,5 to 1 micron and 10 particles in the size range 1 to 5 microns).

Proof of performance: The bar is high – but we´re raising it higher!

Quality class performance in terms of oil contamination, in accordance with ISO 8573.1 makes no statement regardingthe up-stream oil loading entering the filter to arrive at thedownstream performance levels required by the norm.For a few years now (since 2007), an international specificationgoverns the inlet oil loading to be achieved and the test equipment to be adopted, to validate the performance of compressed air filtersin terms of their stated downstream remaining oil content results.

Test methods in accordance with ISO 12500 – Finally a clear statement!

43

A standardised statement regarding the inlet oil loading exists since 2007.A basis has been established against which measurements can be madeand validation undertaken.

44

Stated remaining oil content values, following a high performance filter are in actual fact limited in their meaningfulness. However, where account is taken of the validated inlet-loading in accordance with ISO 12500-1, it becomes clear in what range high-performance filters really do perform.

New GL-Filtration technology delivers what it states and offers you an independent, validated statement of performance in accordance with ISO 12500-1.

Parker Zander “GL-Filter series Coalescing principle

46

Why an external drainage layer again? The new ISO 12500-1 establishes high levels of separation duty to be performed. With 40 mg of oil inlet concentration, performances of 99,95% are not achievable with filter elements containing a thin internal drainage layer. In 1990 and the years to follow, the internal drainage layer was second to none in comparison with an external „foam sock.“ (compatibility problems, low resistance to pulsation).

Furthermore the new „drainage sock“ represents a new material with oleophobic properties. This is no longer comparable with the less stable foam from two decades ago. Since that time materials technology has made considerable improvements in performance and reliability.

Why filter elements with an external drainage layer?

47

• Liquid repelling material achieves excellent drainage results.

• Max. operating temperature 80°C where an internal float-drain is installed and 100°C with a manual drain.

• Resistent to all mineral and synthetic compressor oils.

Old, used compressor oil

48

“No wet feet!”

• No “wet-band” formation, no etra turbulent-free zone. Optimum drainage – bottom end-cap shrouded in drainage material.

• Traditional filter elements exhibit a wet-band around the base.

• 40% more flow through a small filter element where “wet-band” formation is prevented.

49

• Cast housing-ribs compress the lower part of the filter element and encourage liquid coalescence via capillary forces.

Parker Zander “GL-Filter series” Putting on the pressure – but not at all cost!

57

• In order to maintain the required operating pressure, the resistance to flow, caused by pressure drop must be compensated for by increased compressor performance.

• Results: increased energy requirements, premature compressor wear and an increase in overall cost.

• Conventional filters build up an average 200mbar pressure drop, over and above their initial pressure drop, during the first year of operation

• Differential pressure gauges (Optional) – For the indication of a high, premature differential pressure.

Pressure drop costs money!Pressure resistance

Assumption: Cost of electricity - 0,1 €/kWhCompressor end-pressure 8 bar(a)

58

• Every filter element has a limited economic lifetime. The dirt-holding removal capacity becomes exhausted and the materials of construction age – the result is an increasing resistance to pressure in the filter.

Avoid experiencing unnecessary pressure drop in the first place by refraining from the use of old filter elements!

• Comparison: Compare the investment costs of a new filter element to the energy costs necessary to compensate for the resistance to pressure of a dirty filter element. Its worth changing in time!

This is of value to you: A summary of the benefits

Investing in compressed air filters to save money can turn out to be a costly mistake. After all, they should serve to enable the stringent regulations for compressed air quality to be met, without creating high pressure drop in the system. The resulting additional expenditure spent on energy considerably increases operating costs. Rely on the merits of the new GL-series – a decision you will not regret.
